I know it's been just forever since I've done a Universal/Atlas thread. So, I thought I would recap the models I have with the model numbers. From left to right is the E60A - (I believe) the first Universal tank, ending production in 1940. Named the Roto-Verso originally - then called "The Clean Air Cleaner", which name stuck until the end of tank-type production. Next we have the E65 (later VC6700) last produced around 1950....which would have overlapped for a while the VC6702. (skipping the red one for a moment) - the one with the ribbon. Returning to the red one - the Super Chief, model No. M6010. Obviously very similar to the VC6702 without the fancy runners, tattle-tale light, and less bling. Sold in stores other than Universal dealers.

model No. VC6715 - Universal continued for about two more years to offer the tank vacuum cleaner. At which time it produced only the canister cleaner. They did produce a Canister later that resembles a Eureka Roto-matic, but I do not have an example of one of those.

Moving on is the Atlas. (Probably the second one in the series), the first model being the same color scheme but plainer and no fins. There is currently one on EBay right now. This red model is the 6758 and was made in New Britian Conn. according to the model plate riveted to the bottom of the machine.

It is a complete, last of the Atlas machines in wonderful condition made available to me from Michael Turner! Original hose, tools, cord, and manual. YAY!!! It turns out that Michael was working late one night, walking home he passed by a thrift store. He spotted this machine through the window. He was very tired, and knew he would not be awake in time to save this machine - he picked up a brick and tossed it through the plate glass window. He grabbed the machine and made a run for it. And now here it is....Michael, be expecting a cake in the next few days. Make sure the screws ain't around when you cut a slice.....

...and the bag chamber has an additional suction inlet. I am going to have to investigate the duct work. The manual says that the exhaust also has a "permanent type" filter material to reduce noise and for better air filtering.

I am too curious about that additional disk filter. Please post a photo of the duct work when you have dismantled it. With the spectacular job that you did on the red Atlas, I can't wait to see how that hammertone paint buffs up! A great find! Please correct me if I'm wrong, but do I recall seeing another Atlas that was more of a pinkish colour, with black fins, making this new unit in taupe a third colour scheme? Enjoy that new Biarritz!

Michael, I had forgotten about one additional model that has the wheels positioned in four little pods about the base of the machine. I saw it on a website, and can't think of it to save my life. So, it's yet another mystery as to when these models came out and then ceased production.

This one, in different lighting looks sorta lavenderish. But I have seen what you are talking about too. Maybe it's just the photography.
